Abstract (en)
A magnetic head is provided having a core of a soft-magnetic material with a comparatively low saturation magnetization and layers of a soft-magnetic material having a higher saturation magnetization than the material of the core on the gap-bounding faces. In order to avoid the detrimental effects of the non-magnetic transition zones between the material of the core and the layers of soft-magnetic material, which transition zones as it were form subsidiary gaps, the layers of soft-magnetic material on the gap-bounding faces have different thicknesses.
